功能說(shuō)明：

該二位四通和三位四通比例方向閥為直控，板式結(jié)構(gòu)；由比例電磁鐵操作，比例電磁鐵帶中心螺紋，線圈可單獨(dú)拆卸，電磁鐵的控制可通過(guò)外部放大器（WRA型）或內(nèi)置的放大器（WRAE型）實(shí)現(xiàn)。

該閥由下列部分組成：

——帶安裝底面的閥體（1）

——帶彈簧（3）和（4）的控制閥芯（2）

——帶中心螺紋的電磁鐵（5）和（6）

——位移傳感器（7）

——可選帶內(nèi)置放大器（8）

——通過(guò)Pg13.5可以機(jī)械零位調(diào)整（9），4WREE型通過(guò)Pg7（10）可以電氣零位調(diào)整

工作原理：

——電磁鐵（5）和（6）不帶電時(shí)，對(duì)中彈簧（3）和（4）將控制閥芯（2）保持在中位

——比例電磁鐵得電被激勵(lì)后，會(huì)直接推動(dòng)控制閥芯（2）

例如：控制電磁鐵“b”（6）被激勵(lì)

→控制閥芯（2）被推向左側(cè)，位移與輸入電信號(hào)成比例

→這時(shí)，P口至A口及B口至T口通過(guò)閥芯與閥體形成的節(jié)流溝通并具有漸進(jìn)的流量特性。

——電磁鐵（6）失電

→控制閥芯（2）被對(duì)中彈簧（3）重新推回中位

在電磁特失電的情況下，閥芯（2）在電磁鐵復(fù)位彈簧的作用下保持在機(jī)械中位。這對(duì)機(jī)能符號(hào)“V”的閥芯來(lái)說(shuō)，與液壓中位無(wú)關(guān)！當(dāng)閥用于閉環(huán)控制而關(guān)閉時(shí)，閥芯則置于液壓中位。
